Diesel fuel prices in the United States are rising rapidly, particularly in four Midwestern states that have already set new all-time highs, leading to increased prices for food and consumer goods.
Foreign news agencies reported on 13 May 2026 that diesel prices, a vital fuel for the U.S. economy, have surged to unprecedented levels in four Midwestern states—Wisconsin, Michigan, Illinois, and Indiana—due to the U.S. war with Iran, which has effectively closed the Strait of Hormuz.
Data from the American Automobile Association (AAA) shows that average diesel prices in these states reached record highs last Wednesday.
The recent rise in diesel prices results from multiple factors including elevated crude oil prices, refinery disruptions, and refineries prioritizing jet fuel production over diesel and gasoline.
Diesel is central to the U.S. economy, powering tractors, trucks, buses, trains, and ships. Rising diesel costs could increase prices for food and consumer goods because of higher farming expenses and transportation costs to retail outlets.
Currently, the national average diesel price has jumped 60% compared to pre-war levels, reaching $5.66 per gallon, approaching the all-time high of $5.82 per gallon recorded in June 2022 after the Ukraine war began.
Diesel prices in these four states have risen faster than elsewhere: Indiana +72% at $6.13 per gallon, Illinois +74% at $6.13, Michigan +77% at $6.13, and Wisconsin +82% at $5.87 per gallon.
